Came to a full stop on the snout shaft as run out of 1" bar so turned my attention to sorting the intake out, I'm gonna have to use the Fenton 3 x 2 as can't find an aluminium intake to mill out, Only one person making one and its big money, there is one guy making blower intakes for the Y block but at $1000 he can keep them !!!
The problem I have is the carb throats on the Fenton are too far apart for the bottom outlet of a 4/71, a 6/71 would of been spot on but way to big for the look I want. Anyways decided to stick with what I have, shame really as the Fenton seems to be fairly rare.
My cunning plan is to fabricate a curved ended box to act as a plenum which simply bolts to the existing intake and the blower bolts straight to this.

First job was to make a 3/8" plate for the base and transfer all the various holes, the original carb mounting holes will be drilled out to 3/8" as because of the top having the normal 5 degree inclination the holes will be slightly tilted once I flycut the top surface true to the crank centreline, the pics hopefully will explain.










Here I have made a mockup in cardboard.










Getting to the rear 2 and the front 1 mounting bolt will be tricky but doable
